Pepper's bit at the end was excessive and out of sync with the rest of the film (and the franchise to date).

But my biggest issue with the film were Tony's actions and dialogue with the boy Harley. Very mean, insensitive, and simply uncalled for. I have never seen an adult talk to a child in such a crude way in real life or on a screen.

And the other part that spins off of that is Harley looking for a father figure. Tony completely ignores this and makes fun of the boy even further.
